VALLEY aoorme.

Application filed January 6, 1921. Serial No. 435,465.

State of Pennsylvania, have invented cer-.

tain new and useful Improvements in V alley Roofing; and I do declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in roofing and more particular y to valleys, and the principal object is to provide a novel form of valleyroofing for use principally in connection with slate roofs, although usable to equal advantage with cement shingles, asbestos shingles, and merous other well known roofing materials, novel provision being made whereby the use of tin and the like is dispensed with, substituting therefor a plurality of wear-resisting shingles mounted in a unique manner upon a sheet of flexible water-proof material.

With the foregoing in view, the invention resides in the novel construction and association of parts hereinafter described and claimed, the descriptive matter being supplemented by the accompanying drawings.

Figure 1 1s a perspective view showing my invention applied to a valley.

Figure 2 is a transverse sectional view as indicated by line 2-42 of Fig. 1.

Figure 3 is a; sectional perspective View of one form of constiyuction, and Fig.4 is a similar view showing another form.

In carrying out my invention, I employ a sheet 1 of appropriate having water-proof and wear-resisting. qualities, this sheet being preferably about three feet long and eighteen inches wide although these roportions are not absolutely essential. ecured by any appropriate non-drying cement, to the upper surface of the sheet 1 are two longitudinal rows of shingles 2 which are formed of slate, cement, or any other appropriate water and wearproof material. However, slate is preferably used and small scraps may be utilized which would otherwise be thrown away. The inner ends of the shingles of one row are spaced slightly from thecorresponding shingle ends of the other row so that the sheet may be longitudinally bent on a central line 3 so that it may conform to the flexible material angles of different valleys. If desired, the

bending-line of the sheet 1 may be reinforced on its lower side by a strip of fabric or the like as designated by the numeral 4, but th s is not in all insta-nces necessary as will be clear by' reference to Fig. 4. This strip may be made of any suitable material am of one or more thicknesses as desired.

The slight space between the inner ends of the two rows of shingles 2, is preferably filled with an asphalt cement or other appropriate pliable. non-drying cement, this cement being applied while the sheet 1 is in the flat form depicted in Fig. 3. It thus follows that when the sheet is bent along its longitudinal center 3, the cement 5 will be compressed as will be clear by reference to Fig. 2 causingthis cement to enterany existing crevices at the lower ends of the shingles and between these shingles. This cement serves to effectively anchor the lower ends of the shingles 2 to prevent them from possibly separating from the sheet 1 and in addition, it receives all wash of water running down the valley, which would otherwise act directly on the bent intermediate portion of the'sheet 1.'

Both edges of the sheet 1 extend beyond the outer ends of the shingles 2 for the purpose of roviding a pair of nailing flanges 6 throng which the nails .7 are driven for securing the device to the roof '8, and-the upper end of said sheet extends preferably about six inches beyond the uppermost shingles to provide a flange 9 which is adapted to be overlapped by another sheet or section of the-valley roofing as depictedin Fig. 1. When the valley is laid by using a plurality, of roofing sections constructed in accordance with'this invention, it will be absolutely water-tight and will present a very neat appearance, and no rusting out will occur, as is the case with the-usual metal valley now commonly employed. Furthermore, no paint or other surface coating is required and no repairs are necessary from time to time. The usual shingles overlap the outer ends of the shingles 2 as will be clear from Fig. 2 of the drawing and if desired a pliable cement filling 10 may be employed between wish it understood that within the scope of the invention as claimed, numerous minor changes may be made,

I claim:

1. A roofing section for valleys compris ing an elongated sheet of flexible waterproof material, and two rows of shingles secured on said sheet, said shingles extending transversely. of said sheet, the shingles of one row having their inner ends spaced slightly from the corresponding shingle ends of the other row, permitting bending of the sheet into conformity with a valley.

2. A roofing section for valleys comprising an elongated sheet of flexible Waterproof material, and two rows ofshingles secured on said sheet, said shingles extending transversely of said sheet, the shingles of one row having their inner ends spaced slightly from the corresponding shingle ends of the other row, permitting bending of the sheet into conformity with a valley, one end of said sheet and both edges thereof extending beyond the shingles for the purposes set forth.

3. A roofing section. for valleys comprising an elongated sheet of fiexible w'aterproof material, and two rows of shingles secured on said sheet, said shingles extending transversely of said sheet, the shingles of one row having their inner ends spaced slightly from. the correspondingshingle ends'of the other row, permitting bending of the sheet into conformity with a valley, the space between the two rows of shingles being filled with pliable non-drying cement.

4. A structure as specified in claim 1; together with a flexible reinforcing strip secured to the lower side of said sheet along its bending line.

In testimony whereof I have hereunto set my hand.

I JAMES H. MUNRO.
